PinkSale Finance is not a scam. It is a legit decentralized launchpad protocol that supports several blockchains. Launchpads are platforms that make it easier for people to create, promote, and sell their tokens. Some coins launched at PinkSale Finance may turn out to be scams and that is another story if someone understands the crypto world, even Binance Smart Chain launchpad has had some coins launched which eventually rug-pulled.
PinkSale is accountable for more than 8730 launchpads, $380 million in liquidity, and $415 million in locked value.
So far there is nothing that points PinkSale Finance to be a scam project.
